| titleOfInvention | Method for Purifying Ethyl Tert-Butyl Ether by Permeation Treatment with Membrane and Distillation |
| abstract | The present invention relates to a process for separating a mixture consisting mainly of ethyl tertiary butyl ether (ETBE), ethanol and C 4 hydrocarbons.n n n The process of the present invention comprises injecting a mixture to be separated into a debutane to recover C 4 hydrocarbons with some ethanol at the head and recovering purified ETBE as a bottom product; Extracting the sub stream of ethanol-rich phase and feeding it to the permeation treatment zone; And recovering the residual product free of ethanol from the permeation treatment zone with a debutane and recovering the permeation product based on the separated ethanol, wherein the permeation treatment zone is N, N-dimethyl aminoethyl methacrylate. A high density film of a film made of a polymer (DMAEMA) or a copolymer of DMAEMA with N-vinylcaprolactam (NVCL) and / or N-vinyl pyrrolidone (NVP).n n n The process of the invention can be integrated into the ETBE manufacturing process, where the ethanol separated during the permeation treatment step is recycled to the etherification reactor. The debutane group can be replaced by a catalytic distillation column. |
